Did anyone see that big "Once Upon a Time" twist coming? (Answer: We did!) In Sunday night's jam-packed season three finale, Emma (Jennifer Morrison) and Hook (Colin O'Donoghue) went on a time-traveling adventure after getting sucked into Zelena's (Rebecca Mader) treacherous portal.

Who are we kidding, what we're dying to talk about is the new queen among us!

After landing safely back in Storybrooke, it seems that Emma and Hook accidently brought a chilling surprise along with them. In the episode's final seconds, fan were treated to a quick glimpse of a girl with gorgeous blonde locks and an icy touch. Ladies and gentlemen, it appears that Princess Elsa from "Frozen" has landed in Storybrooke!

We have been championing for the "OUAT" writers to bring the Arendelle sisters to the small screen for months now, so we're thrilled that our persistent nagging (Ahem, we mean suggestions) have finally paid off.

When we chatted with "Once Upon a Time" producers Eddie Kitsis and Adam Horowitz in March about bringing the "Frozen" actresses Idina Menzel and Kristen Bell to Stroybrooke, the magical twosome was very excited at the prospect. "I mean, we would be completely honored if either one of those two wanted to do our show," Kitsis exclaimed. "I can tell you that in the 'Once' writers' room, it has turned into the 'Frozen' Appreciation Society."

The creator continues, "We are so in awe of that movie. A lot of us have children, and we are obsessed with that movie in a way that like, it's inspiring to all of us."

Who Should Play Elsa From "Frozen"? Fans know Elsa as the snow-loving queen, whose icy first impression slowly melts away once you get to know her. Not only is she an independent lady, she fully endorses the notion that you shouldn't marry a guy you just met five minutes ago--a lesson that many of our Disney princesses could definitely learn. We think that Dakota Fanning, Dianna Agron and Megan Hilty have what it takes to rule their very own ice palace, but who do you think would lead Arendelle with the same poise and grace as Elsa?
